For the first time, clumps of human cells called organoids were fully integrated with the brains of rats—and influenced their ...

Vaults are mysterious cellular structures that can be genetically engineered to store information about a cell’s history.

After centuries of mapping the human body in ever-finer detail, scientists are still making discoveries. Here we are, in 2025, and a previously unknown cellular structure that could be vital to our ...

The human body has always been crowded with microscopic passengers, from bacteria to viruses and fungi. Over the past two ...

Researchers find obelisks, mysterious RNA molecules in human bacteria that challenge our understanding of viruses and microscopic life.

Cells shrink a major internal structure as they age. New research shows this downsizing is deliberate—and linked to longer ...

The lab has developed ultra-small DNA nanodevices that can function inside living cells, illuminating biological processes.

Researchers at the University of Washington and Fred Hutch found that CARD8, an inflammasome sensor, detects HIV-1 in macrophages during cell-to-cell viral transmissions from infected T cells. HIV can ...

YAHOO.COM - Sixty years after scientists described the chemical code of life — an interweaving double helix called DNA — researchers have found four-stranded DNA is also lurking in human cells. The ...

DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave. Researchers have now mapped this hidden architecture in unprecedented detail, showing ...

Instead of killing bacteria, scientists found a way to gently guide gut microbes to produce compounds linked to longevity and healthier aging.
